What is 3D Electromagnetic Simulation?

3D electromagnetic simulation describes approaches to solving Maxwell's equations in space and time. Methods based on volume discretization are, for example the finite element method (FEM) , the finite integration technique (FIT) , the finite difference time domain method (FDTD) , and the transmission-line matrix method (TLM) . These methods are very general and can be used to simulate all classes of problems. However, there are methods that are far more efficient for specific problem classes, such as the method of moments (MoM), boundary element method (BEM) mode matching and physical optics.

What are Fullwave Electromagnetic Simulation Methods?

Fullwave em-simulators solve Maxwell's equations without approximations based on a problem's special physical nature. They typically provide solutions to high-frequency electromagnetic applications such as antennas or components. SIMULIA provides time-domain and frequency-domain em-simulators.

What is the Best Electromagnetic Simulation Software?

The best electromagnetic simulation software is the one that gets the job done accurately and quickly. One fundamental requirement to accomplish this challenge is the availability of a variety of numerical simulation methods within one software package because not one simulation tool can solve all the simulation challenges . The SIMULIA electromagnetic simulation portfolio offers a wide range of em-simulators for frequency ranges from DC to light.

What is the Basis of Electromagnetic Simulation?

Numerical simulation of electromagnetic fields is typically based on a discretization of Maxwell's equations in space and time. In the simplest FDTD case, the simulation volume is mapped onto a Cartesian grid. The individual grid cells can be filled with different materials and the electric and magnetic fields are defined along the edges and through the facets of the cells.
